The Research

What the Research Says About Outcomes for Youth Who Have Coaching

Independent research consistently backs up what coaching families experience firsthand — that having a dedicated adult mentor outside the immediate family produces measurable improvements in a young person's confidence and wellbeing. Here's what the actual data shows.

Effect size when a mentor is matched to a youth's actual interests — nearly double the 0.20 seen without that match

Effect size specifically for self-esteem in a 2021 meta-analysis — the strongest emotional outcome studied

The honest baseline: mentoring works, but modestly on average

The most cited meta-analysis in this field, reviewing 55 separate evaluations of youth mentoring programs (DuBois et al.), found an overall effect size of 0.18–0.21 — described in the research as a modest-to-small benefit for the average youth in an average program. It's worth being upfront about that: mentoring is not a guaranteed transformation, and generic, low-touch programs show only modest average effects.

Why personalization roughly doubles the impact

Here's the important nuance. That average number changes significantly based on program quality. The same research found that when a young person is matched with a mentor based on shared interests, the effect size nearly doubles — 0.41 versus 0.20 for those who weren't matched this way. In plain terms: mentoring that's genuinely personalized to the young person produces roughly twice the impact of generic mentoring.

Where the research shows the strongest results: confidence itself

A more recent meta-analysis focused specifically on emotional wellbeing (Claro & Perelmiter, 2021) found that mentoring produced a medium positive effect on self-esteem specifically — notably stronger than its effect on other outcomes like general negative affect. That suggests mentoring's strongest impact shows up precisely where Teen Clarity Lab focuses: confidence and self-perception.

What this means in practice

What this research consistently points to is that mentoring works best when it's personalized, relationship-driven, and specifically focused on confidence — not generic advice delivered at scale. That's the entire premise behind how Teen Clarity Lab is built. It's also reflected in our own numbers: teens coached through Teen Clarity Lab have self-reported a 78% increase in confidence after three to six months of coaching — a result that sits well within, and even above, what the broader research on high-quality, personalized youth mentoring would predict.
